DEVICE FOR EXTRACTION OF DISSOLVED GASES, MAINLY FROM SEA WATER Russian patent published in 2025 - IPC C02F1/20 C02F1/38 B01D19/00 

FIELD: performing operations.

SUBSTANCE: invention relates to hydraulic engineering, power and chemical industry, can be used for separation of gases dissolved in water, for example hydrogen sulphide and ammonia, independently in continuous mode. Device for extraction of dissolved gases from liquid comprises housing, liquid cavitation treatment system and liquid feed pipe. Device is equipped with a chamber made in the form of a torus of variable cross-section with ratio of minimum to maximum cross-section area of not less than 1/10 and a branch pipe for discharge of gas-liquid mixture, which is connected to a gas separator. System of cavitation treatment of liquid contains a ferromagnetic liquid placed in a chamber, phase electromagnets, windings of which are placed on top of the chamber at equal distances from each other, an electronic switch, a clock generator of pulses, a microcontroller and a sensor of magnetic field positioning. Magnetic field sensor is made in the form of a float. Outputs of electronic switch are connected to windings of phase electromagnets and clock pulse generator. Input of the electronic switch is connected to the output of the microcontroller, and the output of the rotary magnetic field positioning sensor is connected to the input of the microcontroller.

EFFECT: invention simplifies the design of the device, increases reliability of its operation, eliminates the need for periodic maintenance and provides autonomous operation.
